Installation on critical substrates

When carrying out building conversions or renovation work, one often encounters critical substrates, which have to be levelled, de-coupled and impact sound transmission reduced before installing tiles. Here the impact sound deadening and de-coupling board STEPBOARD can be used. To reliably prevent offsets in level, it is recommended that existing cracks in the substrate are adhesively sealed, e.g. ASODUR-K900.
